Agent Sledge and Agent Hammer
The climactic "balancing platform" sequence was directly inspired by this cartoon, which is mentioned in the credits.
The guy whose range rover (British equivalent of the humvee) is commandeered by Ed Harris in National Treasure 2 (2007) is the same man who's humvee is commandeered by Sean Connery in The Rock's (1996) San Francisco chase scene (the man is Hans Georg Struhar, and these are his ONLY two acting roles; normally he appears to be a wardrobe guy). He has a distinctive foreign voice and gives the same startled reaction in both movies. Both films were produced by Jerry Bruckheimer and starred Nic Cage and Ed Harris.
Jon Voight tells a story about 'Franklin Delano Roosevelt''s wheelchair in National Treasure: Book of Secrets, having played FDR in Pearl Harbor.
